UNITED STATES PATENT OFFICE.

OTTO ERNST, OF NEV YORK, N. Y.

IMPROVEMENT IN TOBACCO-PIPVES.

Specification forming part of Letters Patent No. 35,926, dated July 22,1862.

To all whom t may con/cern,.-

Beit known that I, OTTO ERNST, of the city and State of New York, haveinvented, made, and applied to use a certain new and useful Improvementin Tobacco-Tubes; and Ido hereby declare that the following is a full,clear, and exact description of my said invention, reference being hadto the annexed drawings, making part of this specification, whereinFigure 1 is a longitudinal section, and Fig. 2 is an end view.

Similar letters denote the same parts.

My invention consists in a' smoking-tube made of glass, with a slidingglass tube forn1- ing a piston for forcing the tobacco forward asconsumed, said glass smoking-tube or pistoirpipe" forming a new articleof manufacture.

I am aware that smokingtubes of porcelain, metal, and wood have beenmade with a piston 5 but the same have not been adapted to the publicdemand, because they speedily become offensive from the oil of thetobacco pene trating the material and lodging in the pipe, where itcannot be cleaned. By my peculiar construction of glass piston-pipefacility is given for cleaning, and the glass itself can easily be keptclean and the operation of smoking be observed.

In the drawings, a is a tube of glass. b is a perforated cork or otherarticle closing one end of this tubea and forming the slide for the tubec, that passes through the same. This tube c is to be of glass andprovided with an enlargement, d, at or near one end within the tube a,and with a properly-shaped end at e to enter the mouth of the smoker.

Tobacco is to be placed in the tube a, as at f, and made sufficientlycompact by pressing in the tube o with the end d against said tobacco,and when lighted the tobacco is con.- sumed as usual, except that themass is forced along from time to time by the piston or end d of thetube c, in order that the re may be at the outer end of the tube a. Eachtime the tube c should be drawn back, in Order that it may not becomeobstructed by any pieces of tobacco or other substance drawn into thesaid tube c.

My tobacco-tube is light, cheap, and portable, and when not in use shutsinto a very small compass, and the ashes and fire can always be keptprojecting from the end of the tube a by the action of the piston d.-

In place of the tube c sliding through the cork b, said cork' or othersuitable packing may slide with the tube c in the tube a. This tube iseasily kept clean, and the smoker can see everything in his pipe, so asto remove any obstruction or deposit of oily matter from the tobacco,and the glass is so smooth as not to injure the packing as the piston ismoved backward and forward, hence my piston-pipe will remain air-tight.

IVhat I claim, and desire to secure by Letters Patent, is

The piston pipe or tube formed of glass in the manner specified, andconstituting a new article of manufacture for smoking tobacco, as setforth.

In witness whereof I have hereunto set my signature this 1st day ofNovember, 1861.

OTTO ERNST.
